Incoming Serious Weather Warning in Mississauga

We've had a few tough scorchers in July so far, but the worst may be yet to come.

Mississauga, as well as other cities in southern Ontario, can expect some high temperatures starting this week from Tuesday to Thursday, according to a recent statement from Environment Canada.

The cause is a hot and humid airmass coming from the Gulf of Mexico, which is expected to arrive during the day on Tuesday.

The weather agency said heat warnings will likely be issued later today.

Temperature highs of 30 to 33 can be expected in most places, with overnight lows of 20 to 23. Wednesday and Thursday may be slightly cooler due to the possibility of showers or thunderstorms, as well as a cooler airmass expected to move in Thursday night.
